MP Materials Launches US Rare Earth Magnet Production at Texas Plant
MP Materials has launched its first full-scale domestic manufacturing facility in Fort Worth, Texas. This initiative aims to reduce dependence on foreign suppliers, particularly China, and establish a self-sufficient supply chain for critical components used in electric vehicles, defense systems, robotics, and consumer electronics.
Rare earth magnets, primarily composed of neodymium, praseodymium, and other elements, are essential for high-performance electric motors and advanced technologies. The US has long relied on overseas sources for these materials, creating vulnerabilities in national security and industrial supply chains.
A Key Milestone in US Magnet Manufacturing
MP Materials’ new Fort Worth facility is designed to produce both neodymium-praseodymium (NdPr) metal and sintered neodymium-iron-boron (NdFeB) magnets. These magnets are vital for high-efficiency motors used in electric vehicles and other applications. The new facility is expected to deliver approximately 1,000 metric tons of finished magnets annually once fully operational.
One key advantage of this facility is its integration with MP Materials’ Mountain Pass mine and processing operation in California. The Mountain Pass site produces rare earth oxides, which are then refined into materials for magnet production. This end-to-end supply chain ensures the US has direct control over rare earth magnet production, mitigating geopolitical risks and supply disruptions. Production at the Fort Worth plant is expected to ramp up gradually, with commercial-scale manufacturing of precursor materials beginning in mid-2025 and full magnet production by late 2025.
MP Materials’ Partnership with General Motors and Broader Industry Impact
A major driver behind MP Materials’ expansion into magnet production is its long-term supply agreement with General Motors. Under this agreement, MP Materials will supply rare earth materials, alloys, and finished magnets for use in GM’s EV motors. These magnets will be critical for electric models such as the GMC HUMMER EV, Cadillac LYRIQ, and Chevrolet Silverado EV.
This partnership strengthens GM’s North American supply chain and reflects a growing trend among US manufacturers to secure domestically sourced critical materials. The automotive industry, which relies heavily on rare earth magnets for EV production, is expected to benefit significantly from this shift toward onshore manufacturing.
Beyond the automotive sector, MP Materials’ expansion impacts industries including defense, aerospace, and consumer electronics. Rare earth magnets are essential for fighter jets, missile guidance systems, medical imaging devices, and wind turbines.
Economic and Strategic Implications of US-Based Rare Earth Production
MP Materials’ investment in the Fort Worth facility is part of a broader $700 million initiative to restore the US rare earth magnet supply chain. This project is expected to create approximately 150 direct high-skill jobs and an estimated 1,300 indirect jobs, contributing to local and national economic growth.
The resurgence of rare earth magnet manufacturing in the US also carries significant strategic benefits. The Department of Defense has long expressed concerns over reliance on foreign-sourced rare earth materials, particularly from China, which dominates global rare earth magnet production.
MP Materials has also signaled interest in exploring new processing technologies and refining methods to enhance the sustainability and cost-effectiveness of rare earth magnet production. Research and development in this field could lead to breakthroughs that strengthen the US supply chain and reduce environmental impacts associated with rare earth mining and processing.
